  • Cooler and power electronic module having the same
    Patent number: 9955613
    Abstract: The present disclosure provides a power electronic module that includes a first power device having a first switching element and a second power device having a second switching element. The power electronic module further includes a cooler having a coolant passage to cool the first and second power devices. The cooler includes a first inner fin and a second inner fin in the coolant passage. The first power device and the second power device are disposed along a flow direction of the coolant passage so that the first power device is arranged on an upstream side of the coolant passage from the second power device. The first inner fin and the second inner fin are disposed along the flow direction corresponding to the first and second power devices so that the first inner fin is arranged on the upstream side from the second inner fin. The first inner fin has a corrugated passage and a straight passage. The straight passage bypasses the corrugated passage along the flow direction of the coolant passage.
